The concept of the app is very clear. u can watch videos anytime anywhere . no tension but u need internet. also now the new feature is offline saving wich is best if u internet is slow.
the best part is u can see anytype of video from any corner of the world .
the layout and design is very classic and very cool and nice looks very elegant and is also loaded with full of features.
the only disadvantage of offline video save is it cant be shared with anyone .
the app is aslo very usefull for study and for cooking purpose and also if u have any doubts in any field u will surely get ur solution in the youtube that too very fast . and which is very much usefull. so thanks to youtube and susajan wojocicski the ceo of youtube.
